Description
The device changes the connection or the range of the windings with the transformer disconnected and is not operated under load. The standard version has 2 positions, the special version 3. The reversing switch is selected for power transformers of the Um 123–170 kV class, where the winding connection is changed when putting the unit into service or when the network mode changes. The rated through current depends on the number of phases of the device.
